SURGTCAL BAKER.

Application illed January 28, 1922. Serial No. 532,461.

To all lwhom t mag/concern.'

Be it known that I, WALTER S. EnMANns, a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, have' invented a certain new and useful Improvement in Surgical Bakers, of which the following is a specification, reference being had therein to the accompartying drawings.

`The invention relates to a new and useful improvement in bakers for surgical purposes.` It relates especially to that vclass of such bakers as are adapted to embrace or partially embrace the body or limb of thevpatient. Inthe preferred form of construction the baker comprises two o! more segmental members hingedvtogether at their upper kends so that the lower ends may be brought eithercloser.4v together or farther 50 apart according tothe conditions and according to the size of the body or ylimb which is intended to be embraced. The present invention, however, is applicable to a device whether made of a single rigid 3,5 segment-shaped member or a plurality of segment-shaped members hinged together. In devices of this character heating instrumentalities are provided on or adjacent to the inner periphery of the yse,ement-shaped Wimembers and the inner periphery of said members is formed with reflecting surfaces to throw the heat against the'body or limb of the patient. The usual 'and preferred form of, heating.,instrumentalities is electric lamps. As heretofore constructed. these lamps have kbeen' soexposed 'that unless eat care is exercised there is danger of t e lamp coming in contact with the body of the patient or with the hands of the 4 operator who is manipulating it, thereby causing dangerous burns. The outside periphery also of the segmenbshaped members becomes highly heated and the hands of the operator sometimes are burned by coming in contact with the heated surface. The objectof the present invention is to provide a suitable guard to protect the operator and the patient from direct contact with the lamps or with the heated surface of the` said embracin 'members of the baker. The invention will be fully understood fromthe following description when taken in connection with the accompanying' drawings, and the novel features thereof will be pointed out and clearly defined in the claims atl the close of this specification.

In the drawings, Fig. 1 is a side elevation of a device embodying the invention.

Fig. 2 is a section on line 2 2 of Fig. l.

Referring now to the drawings, the supporting frame for the reflector, lighting and heating apparatus consists of two segmental side plates 1, 2 at each side of the apparatus which are pivotally connected as to hold them tightly together, but this also does not form a part of the present invention and is, therefore, not shown in detail in the drawings nor described herein.

Each segmental side plate 1, 2 is connected ywith `the corresponding side plate 1. 2 at the opposite side of the device by' a plurality of tie rods. As shown in the drawings each pair of segmental members is tied 'together near its lower ends 'by the transverse tie rods 6, 7 the tie rods 6 being near the outer periphery and the tie rods 7 being near the inner periphery. They yare also tied together by an intermediate tiev rod 8 near' rthe' outer periphery intermediate between the upper and lower ends of the side plate. Each pair of side plates are tied together at their upper ends by meansof the pivot screws 3-and 4 respectively which engage with a stitfening rod 9 around which `thel upper edge of the reflector plate l0 is curled.

Each reflector member consists of a curved plate 10 preferably of metal which isfbenty to the proper shape, preferably in the form of the segment of a cylinder and has ran inner reflecting surface. Said reflector is o f suicient width to bridge the space between the two oppositeside plates ll and 2, 2. p

any suitable means for furnishing light and heat for the baker may be employed, the means shoirn being similar to that shon'n 5i the patent to lll. Edinands and C. it. ioyt. lilo. T"',i05, dated )lorem i lier i901, and n itselt "ns no part of the present inrei led.

th" heating and l l 'fing r electric lamps li ntted in Aached to the side plates l L ratus, and these lamp a e up and provided with well with rods side sutilthe lai` A i3 extending transversely fr plate to tie other. said rods x cientl.v short intervals to answer the purposes of a guard and at the same time not being Yso frequent as to obstruct the passage ot the heat and the light. These rods .may be made ot any suitablo heat resisting substance. Preferably they are metal rods haying a-tubular covering ot hard fibre or other heat resisting material. The lowermost tie rods 7 may be also utilized as a part of the heat guard by covering them with a hard fibre tube the'same as the others.

rl`here are also provided a plurality of heat protecting rods 1-l a short distance radially away from the outer surface ot the reflector, as shown in the crawings, these protector rods being ot heat resisting outside covering similar to the rods i3.

In order to form a mount ior these heat protecting rods both on the inner and the outer sides ot the apparatus, there are preferably provided brackets 15 which are attached to the outer sides of the side plates l, 2, extending radially of the said side plates and projecting radially outward and radially inward from the side plates, and these protector rods are secured at their ends to said brackets. y

The protector rods are thus spaced away :trom the surface of therefleotor on the outer periphery, and are between the patient and the lamps on the'under side.

. lVhat l claim is:

l. A. surgical baker having a frame portion, heating elements mounted on the trame portion in position to have the heat directed toward the patient. and heat resisting members secured to the iframe which protect the heating elements from coming in direct contact with the patient, the said heat resisting members having open spaces between them to permit passage of the heat to the patient.

2. A surgical baker havingr a reflector portion tor embracing the limb or body of a patient, heating elements on the inner periphery of the reflector member, and heat resisting members to guard the hea-tl provide a plurality ot ing elements from coming incontact with the person ot the patient or Operator, the heating lements being between the reflector and the heat resisting members, said heat resisting members having open spaces between them lfor the passage of the heat to the patient.

il. A. surgical baker having a reflector rtic-n for embracingr the limb or body of a lient, heating elements on the inner pe ol' the reflector member. and a pluheat resisting members extending .1 'ne reflector at some distance radially rward from the inner periphery thereot spaced apart from each other, the .ting elements being between said heat resisting elements and the reflector.
